To rill whom itmag concern:

Be it known that I, lVILLI M C. DiLLoN, a citizen of the United States,residing at Fort Dodge, in the county of Webster and State of Iowa, haveinvented certain new and useful Improvements in Auxiliary Looks forVault-Lock Mechanism, ofwhich the following is a specification.

the "bolt mechanism, when the combination locklhas been forced inwardlyby any means or burnt out by a gas or electric torch.

A further object of the inventionis to provide a block rotatably carriedby-a vault .or safe doorand adapted to be moved in the path of the}vault bolt lock; mechanism sion of said spring, said means being adaptedto be thrown out ofoperation when the combinationlockmechanism isdestroyed.

A still further object oftheinventlon 1s to provide a novel means forcarrying the block and spring and for operatively connecting theisametogether. i Other objects and advantages of the invention will appear inthe following detailed description 'takeniin connection with thedrawings, forming apart of this specification, in which drawings: F a Io a Figure 1 IS a fragmentary rear elevatlon of a vault door and frameshowing the improved device applied thereto.

A c 1 j Figure 3 isan vend elevation of the improved device showing the same-ap'plied to avault door the block being shown in full lines, in a'raised' positionand in dotted lines in a lowered position in the path of the boltlocking mechanism. f I a i Referring to the drawings in detail, where insimilar reference characters design ate corresponding parts throughoutthe several Specification of Letters Patent.

views, the letter A indicates the improved attachment for the bolt lockmechanism B of a vault .or safe door C. The bolt mechanism B is adaptedto engage the doom frame D in the ordinary manner and held in engagementtherewith by the combination lock mechanism E. Thevbolt mechanism B,thedoor C, the lframe D and the combination lock mechanism'E are of theordinary or any preferred construction, and the bolt lock mechanism Eincludes the usual bolts 5 connected to the vertically extending bar 6by suitable bolts 7 or other fastening elements. The bar 6 is providedwith the inwardly extending arm 8, which isdisposedin'the path of the.combination lock mechanism E which prevents the slidingthereof when theCOHI- binationhas been set. V i a i The door C includes the the inwardlyextending flange 10 which is arranged adjacent to and-parallel vwith theidinary or any preferred manner. and held in position by a spring, andhav- 1 ing meansfor holding the block out of the path of the boltmechanism agains'tthe ten-.

The improved auxiliary locking device A comprises a rod 13 whichis'adapted to be inserted through apsuitable opening 14 formed in theflange 10. "The opening in the flange 10 may be drilled at any desiredpoint so that the rod 13 can be placed at different vpoints ondifferentsafes or vaults,

opening 14:, the same is held against accifdentaldisplacement by a pairof lock nuts -15J'which engage the o positesides of the flange 10 andfirmly hol erativetposition; The outer faces of the lock nuts 15 may be,if so desired, milled or ,serrated, so th'at'a firm hold may be ob--tained thereon to permit adjustment thereof.

:The-rod 13 extends inwardly from the flange 1 10 directly in rear ofthe connecting bar 6 of'the bolts 5 and extends beyond said. connectingbar. The portion of the rod 13 which extendslbeyond the bar 6 hasthreadablyv mounted thereon a substantiallyrectangular solid block 16.The threaded bore of body 9having d the rod 13 in op 45 and extendsupwardly therefrom across the face of the combination lock mechanism Edoor G, the free end of the block lies in the path of the connecting bar6 for the bolts 5 and prevents operation of the bolts and therebyprevents the opening of the door. The free end of the rectangular solidblock 16 is'normally held in the path of the connecting bar 6 by meansof a contractile helical spring 17 which has its upper terminal bent atright angles'to provide an attaching arm 18 which is extended through asuitable opening formed in the block 16 directly be low the rod 13. Thelower end of the spring 17 is bent co-provide ahook or eye 19, which is'adaptedto be inserted'through any one of a plurality of openings 20formed in the flat attaching foot 21 carried by the lower end ofthevertical attaching bar 22. The rod 13 intermediate itsends isprovided with a diametrically extending opening 23, which is threaded.for the reception of the threaded end 240i the attaching rod 22. Thethread ed end 24 of the-attaching rod extends beyond thebolt and is heldsecurely in place by a suitable nut and lock washer25. The

, opening 23'for the reception of the attaching rod 22 may be located atany desired point and may be provided in the terminal 'o'fthe rodopposite to the'terminal whichis positioned in the opening 14: of theflange '10. I'napplying the device to a safe or vault door, the rod13"is secured-thereto in the manner described above, andjthe block 16 isthreaded to the desired place'on the "bolt Vdirectlyin' rear of theconnecting bar 6, and

the spring '17 then placed inposition.

The plurality of openings 20 areprovided .so as to permit the spring 17to be placed in any desired position according to the adjustment of'theblock '16; To normallyhold the free end of the block 16 out of the pathof the connecting bari6, a cable 26 is extended throughthe same openingas'the spring 17 and is anchored above the same to the reinforcingbar 12as at27; The cable 26 has a turnbuckle construction 28 intermediate itsends so. as to permit the adjustment or tensioning of the cable. Inapplying the cable 26 in position,the same is first anchored to, itsplace above the combination lock mechanism E and then secured to theupper end of the spring 17, and the block 16 is turned on the rod 13,and'the turnbuckle mechanism 28 adjusted until the cable 26 has beenshortened so'as to hold the block- 16in its raised position against thetension of the spring.

lVhen the combination mechanism has the spring therewith. 7

mitt'ing the spring 17 to draw'theblock 16 into the path of theconnecting bar 6 and thus prevent the operation of the bolts 5.

Thespring 17. is so tensioned that when the block 16' is positionedinthe path of the bar 6, the same will form a support for the block andhold the block against displacement, i

When the cable 26 has been severed the same will drop down into thebottom of the safe and vault and thereby prevent the burglar fromreaching the same and pulling the "block back to its normal position.

\Vhenthe device is applied to a safe or vault'door, the location of thesame is made known to the owner of the'same by exact measurement, sothat in case the safe. has

been tamperedwith by unauthorized persons'the rod 13 can be at oncelocated.

thrown in the path of the connecting barl6, a hole is drilled in thesafeor vault door directly above theblock 16 and a hook is insertedthroughthe hole and placed in an opening or socket 29 formed in the freeend of the block for that purpose. The hook is then drawn forward, whichwill'swing the block 16 on the rod 13 and permit the bolt mechanism B tobe operatedi the ordinary mannen-f 1 'iChanges in detailsmay be madewithout departing from th'espir'it or scope of the invention; hut,f V
